Abstract
1399753 Treating waste water CONSOLIDATED FOODS CORP 31 Aug 1972 [8 Sept 1971] 40500/72 Heading C1C [Also in Division B1] In a method of treating a body of waste water, part is pumped through a closed path in which it is injected with oxygen-containing gas and then returned to the main body after being held in a tank under superatmospheric pressure to assist stabilization of the injected gas bubbles. As shown a sump 33 has an inflow 31 which may lead into a particulate bed 75 of, e.g. perforated plastic balls on which a bacterial coating may form, the rate of inflow controlling the overflow through discharge pipe 41. A recycle line 45 leads to in-line air diffuser 59, holding tank 49, line 51 and inflow 31. The pressure in tank 49 is controlled by relief valve 53 and manual valve 56. A biological or chemical treating agent may be supplied from tank 67 under air pressure; a valve 71 controls the rate of supply of additive, a valve 73 may be connected to a timer for intermittent supply, and a valve 63 controls the rate of flow of air of the diffuser. The recycle pump may be actuated by a level switch. A valve 52 enables the pump to empty the sump.
